MACHINE FOR MAKING TWISTED-WIRE STRANDS.

SPECIFICATION forming part of Letters Patent No. 579,563, dated March30, 189'?.

Application filed July 13, 1895. Serial N0. 555,936. (No model.)

To all whom t may concern.-

Berit known that we, JOHN B. CLEAVELAND and CHARLES 'IIERDRICIL citizensof the United States, residing at Indianapolis, in the county of Marionand State of Indiana, have invented certain new and useful Improvementsin Machines for Making Twisted-Wire Strands; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to improvements in machines for making fence-wire,and 'has for its object the construction of a machine to automaticallyproduce a-twisted-wire fencestrand consisting of four wires, which arefirst twisted together in pairs and then the said pairs twisted togetherto form a single strand having the general appearance of a fou r-wirebraided strand such as was patented to John B. Cleaveland July l0,1891i, No. 522,826.

Ve accomplish the objects of the invention by the mechanism illustratedin the accompanying drawings, in which like letters refer to like partsthroughout the several views.

Figure l is a view in perspective of our complete machine; Fig. 2, adetail showing the under side of the front end of the bedplate of themachine and attached parts; Fig. 3, a detail in elevation of the wheelsfor giving the proper tension to the iinished wire before it is reeled,and the figure shows the standards for supporting the Wheels; and Fig. 4is a detail showing the wire produced by the machine.

A represents the bed-plate of the machine, and a the legs on which thebed-plate rests.

B is a transverse shaft mounted in the journalboxes b on the under sideof the bedplate. (See Fig. 2.)

B is a pulley secured to the outer end of the shaft B and is driven bythe belt B2.

the bevel gear-wheel C are the two radiallyalined guideways d, withinwhich are secured the radially-adjustable slides D, which form the seatsfor the vertical shafts D. Mounted upon the upper ends of the verticalshafts D are the wire-carriers D2, which revolve with the verticalshafts, or if it is preferred to make the shafts D stationar.)7 withreference to their supports then the wire-carriers will revolve aroundthe said shafts.

Dsare sprocket-wheels of equal size mounted on the shafts D', wherebythe rotation of said wheels will transmit a rotarymovement to thewirescarriers.

E is a sprocket-wheel mounted on the upper end of the shaft c. The shafto and the Wheel E are both fixed and stationary.

E is asprocket-chain extending around the two sprocket-wheels D3 andaround the wheel E, whereby when the bevel gear-wheel C is rotated andthe wheels D3 carried around the fixed wheel E the wheels D3 will be`rotated around their individual axes by theaetion of said belt, but inopposite directions to the movement of the wheel C'. The diameters ofthe wheels D3 are each the same and are just one-halfof the diameterofthe stationary wheel E. Thisis an essential feature in the constructionof our machine for the reasons as will be hereinafter fully pointed ont.The wirecarriers D2 being secured to the Wheels D3 will also be revolvedwith said wheels.

Mounted on each of the wirecarriers are the two bobbins F F, carryingthe wire.

D'I is a cross-bar supported by the standards d2, which are integralwith the carriers, and d3 is an opening through the bar forming atwisting-plate through which `the two wires twisted wires from thewire-carriers D2 are threaded.

By making the diameters of the Wheels D3 IOO just one-half of thediameter of the stationary wheel E the twisting-bars DT will be giventwice the speed of the twisting-bar C7 and will revolve in a directionopposite to the bar O7. One-half of the double speed of the bars D7 ismade necessary by the rotary movement of the bars around a common centerin a direction which counteracts half of the twist that would otherwisebe given to the wires as they come from the bars D7. The result is thatthe twist given to the two wires forming the twopart strands as theycome from the bars DT is the same in degree but in opposite direction asthe twist given by the bar 0"' to the two two-part strands and enablesus to combine the four wires of the finished cable together in such amanner that all four of the wires can be seen at regular intervals intheir full thicknessthat is, without overlapping and obstructing theview of each other. By this means we are able to produce a moreornamental and bulkier cable than by any other means.

G is a curved standard which is fastened to the top of the bed-plate andis projected upwardly in the manner as clearly shown in Fig. 1. G is atransverse horizontal shaft mounted on the upper end of the saidstandard, and G3 is a grooved wheel over which the wire from the eye inthe bar C7 passes. The bottom of the groove in the wheel G3 isirregular, the irregularities being made to fit the contour of thetwisted fence-strand, so as to secure a hold on the wire and keep itdrawn sufficiently taut.

H, H', and H2 are vertical standards secured tothe bed-plate, and H3 isa horizontal shaft mounted on suitable box-bearings secured to the saidstandards.

I is a shaft mounted parallel with the shaft H3 on box-bearings securedto the standards H and H', but secured so as to be adjustable verticallyand being pressed down by the springs g,as shown in Fig. 3. Thegear-wheel 71y is mounted on the shaft H3, and the gear-wheel t' ismounted on the shaft I, and the two gearwheels intermesh with eachother, whereby when the shaft H3 is rotated the shaft I will be actuatedalso.

I :is a grooved wheel mounted on the shaft I, and I3 is a disk mountedon the shaft H3 and working into the groove in the wheel I. Theperiphery of the disk is corrugated and the bottom of the groove in thewheel is irregular, whereby the wire strand from the wheel G2 (whichstrand is passed between the wheel I and the ldisk I3) is grasped anddrawn upon with av tension regulated by the speed of the said wheel anddisk.

As the prime object of this invention is to produce a four-strand wirehaving the greatest possible bull; as distinguished from a compact wire,we find it necessary to carefully regulate the speed of the wheel G3with relation to the speed of the underlying mechanism for twisting upthe wires, in order that the two primary strands will be broughttogether in the right position at the moment of uniting them. To insurethis nicety of action, the depressions in the groove of the wheel G3 areshaped and spaced to take the swells of the wire with much the sameregularity that the sprockets of a wheel take the links of a chain belt.The wire as it comes from the twisting-plates is held from slipping, andthe speed of the wheel G3, regulated properly to the speed of thetwisting machinery, insures the proper tension and takeup of the wirestrands to bring them together just right.

M is a sprocket-wheel mounted on the shaft H3, and m is a chain beltconnecting the wheel M with the sprocket-wheel G3 on the shaft G', sothat the shaft G will be driven from the shaft H3.

M is a sprocket-wheel on the shaftl H3 and is connected by the chainbelt M6 with the small sprocket-wheel N on the shaft N'.

N3 is a large sprocket-wheel 'on the outer end of the shaft N and isconnected by the chain belt O with the small sprocket-wheel O on theshaft O3, (see Figs. l and 2,) and O3 is a large sprocket-wheel on theshaft O3, which is connected by means of the chain belt b3 with thesmall sprocket-wheel b3 on the driving-shaft B. Thus it will be seenthat the shaft H3 is driven from the shaft B through suitableintermediate gearing whereby the speed will be properly reduced to suitthe requirements for the shaft H3.

R is a shaft mounted on suitable bearings secured to the bed-plate. Itis provided at one end with a sprocket-wheel R', which is connected bythe chain belt R3 with the sprocket-wheel R3 on the shaft H3.

S is a reel upon which the finished wire is wound. Itis mounted 011 theend of the shaft R opposite the end on which the wheel R' is mounted.

T is a feed of any desired or usual constru ction for delivering thewire uniformly to the reel S. Its sprocket-wheel t is driven by the beltR3 in the manner clearly shown in Fig. l.

Having thus described our invention, what we claim as new,and wish tosecure by Letters Patent, is-
